Title: Optical material and production thereof
Inventor: TAKAGI HIROTSUGU
IPC: C03C14/00
Filed: 1989-10-12
Abstract: PURPOSE:To develop the material for nonlinear optical elements by cracking a specific gaseous Si compd. with microwaves to form superfine particulate Si and ejecting the Si from a nozzle to deposit the same onto a base material, then oxidizing the surface of the superfine particulate Si. CONSTITUTION:The inside of a downstream chamber 4 mounted with quartz glass 6 is evacuated to a reduced pressure by an exhaust pump 8. The gaseous Si compd., such as SiH4, Si2H6 or SiF4, is mixed with gaseous Ar and the gaseous mixture is supplied from a gas introducing pipe 12 into a cavity resonator 5. The microwaves from a microwave oscillator are introduced through a quartz window 7 from an introducing pipe 10 into the cavity resonator 5 and discharge plasma is generated in the resonator 5. The gaseous raw materials, such as SiH4, are cracked by the plasma to form the superfine particulate Si which is injected from a reducing and expanding nozzle 11 onto the quartz base material 6 in the downstream chamber 4 to form the deposited film of the Si superfine crystal contg. about 12% H2 generated by the cracking of the SiH4. The Si superfine particle deposited film is then oxidized by steam to form the oxide film 3 of the Si on the surface of the Si crystal nuclei 2, by which the optical material having the nonlinear effect is produced.

Title: Diameter reducing method for solid waste-storing cylindrical vessel and diameter reducing metal mold therefor
Inventor: WADA NORIO
IPC: B09B3/00
Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent a break of a vessel and to smoothly reduce a diameter. SOLUTION: In this diameter reducing method for a solid waste-storing cylindrical vessel D, the cylindrical vessel D filled with solid waste (a) is pushed into a diameter reducing cylindrical metal mold 20 from one end opening along an equal axis, while a diameter of the inner face of the mold 20 is gradually reduced toward the other end opening to reduce a diameter of the vessel D with the diameter reduction taper face. Before the diameter reduction of the vessel D by the taper face, a wall of the vessel D is bent inward to form a groove in the tube axial direction by radially pressing an appropriate position in the circumferential direction of the vessel D. When reducing the diameter of the vessel D by the taper face, the diameter is reduced with further recessing the groove inward. Because the diameter reducing groove is previously formed, the fear of a break of the vessel wall is reduced when reducing the diameter.
